    What to do if my Sanyo MLS-3751L has no sound?
    • T
      Tara BarreraAug 4, 2025
      If the Sanyo Laboratory Equipment emits no sound, first ensure it's not in sound warning mode. If it is, switch to 'Loud' or 'Medium' volume. Note that no sound is normal during sound warning mode. Check the speaker's resistance value; it should be around 8Ω. If there's a short-circuit or wire breakage, replace the speaker. Inspect the housing set X+U(3751) or D+T(3781) for connection issues or wire breaks and correct them if necessary. If problems persist, replace the 'PCB set, control TH set'.
